Folding of inner mitochondrial membrane are called

Options

A. Grana
B. Thylakoids
C. Cristae
D. `f_(0)-F_(1)` structures

Answer

To answer the question regarding the folding of the inner mitochondrial membrane, we can follow these steps:

1. **Identify the Structure of Mitochondria**: Understand that mitochondria are double membrane-bound organelles found in eukaryotic cells. They consist of an outer membrane and an inner membrane.

2. **Focus on the Inner Membrane**: The inner mitochondrial membrane is crucial for its functions, including ATP production. It is highly folded.

3. **Define the Folds**: The folds of the inner mitochondrial membrane are specifically known as "cristae." These structures increase the surface area available for biochemical reactions.

4. **Function of Cristae**: Cristae play a significant role in the electron transport chain and ATP synthesis, as they contain the necessary enzymes, including ATP synthase.

5. **Select the Correct Answer**: Given the options provided (A-graina, B-thylakoid, C-cristae, F0-F1 structures), the correct answer is C - cristae.

Thus, the folding of the inner mitochondrial membrane is called **cristae**.
